To verify and extract signatures and certificates on an Apple .app, you can do (example Mail.app) codesign -dvvvv --extract-certificates /Applications/Mail.app This will save the certificates in DER format, named codesign0, codesign1, etc. These can then be displayed as usual with OpenSSL openssl x509 -inform DER -in codesign0 -text
